Patent DE-2009299-A1 (DE)
Title: Gas-fired tiltable crucible furnace
IPC: F27B14/14
Filed: 1970-02-27
Abstract: Tiltable crucible melting furnace consists of a crucible which is mounted on a bridge like support above the floor of the tiltable enclosed furnace chamber. The flame or hot gases are introduced into the furnace tangentially from the side and a vertical plate is fitted into the space below the furnace support so that a funnel like channel is produced for the flame/gases. The wall is attached to the inner wall of the chamber and end near the centre of the furnace. This construction prevents the exposure of the crucible plinth to the full force of impinging gases and/or flame, which result in its early destruction.

Patent DE-2314162-A1 (DE)
Title: Exhaust-gas control on rolling mill furnaces - includes a chamber with low-level inlet duct which eliminates dampers and pressure differences
Inventor: LOMBARDI ETTORE
IPC: F27D17/00
Filed: 1973-03-22
Abstract: The exhaust gas leaves the furnace by aduct, mounted in the top of the furnace wall, which carries the gas round a 90 degrees bend downwards to an outlet in an exhaust-chamber. The outlet is appreciably below the level of the furnace floor or hearth and the gas flow has to turn 180 degrees in order to travel up the chamber and into the chimney. An air inlet is provided in the exhaust-chamber above the level of the furnace hearth. When the burners heating the furnace are on, the hot exhaust-gas travels down the duct and up through the chamber to the chimney, but as the duct-outlet in the chamber is lower than the hearth, a slight over-press of 1-2 mm water column is created in the furnace. When the burners are switched off, the suction in the chimney pulls air in through the air inlet which constitutes an easier path, and thus avoids the large drop in press. which would otherwise occur in the furnace. No dampers are required on duct, air-inlet or in the chimney. Heat-insulating linings are provided in the chamber and on that part of the duct over the air inlet.

Title: Conveyor belt bottom run unloading system - uses permanent magnets acting on belt steel rope inserts
Inventor: BARAN WERNER DR RER NAT
IPC: B65G21/20
Filed: 1973-10-31
Abstract: A set or permanent magnets are mounted on stationary supports above the lower run of the belt, their fields acting on the steel rope inserts in the belt and tending to pull the whole run upwards against the force of gravity. Supporting rollers can alos be provided above the lower run, to hold it in a stable position and prevent it fouling the magnets. Anisotropic barium- or strontium ferrite can be used as the magnet material. The magnets can be mounted in rows at right angles to the belt, the pole position alternating with successive rows, and on the side furthest from the bottom run the individual rows can be connected together by an iron short-circuit piece.

Title: Hot-water boiler with electrically-heated oil-storage core - is separated into heating-oil container and hot-water container
IPC: F24H7/04
Filed: 1974-04-08
Abstract: The heating-oil container is located separate from the circulating hot water container and is connected to the latter by pipes and to a tubular heating-surface, built into the circulating hot water container. As a result of this separate arrangement, the heating-storage medium can be heated to a much higher temperature than the water, so that the storage volume can be reduced. The control of the water heating stage is through two mutually independent thermostats. A safety valve is located in the top container wall with a discharge duct leading to the base of the housing.
Patent DE-2420327-A1 (DE)
Title: Recording disinfectant content of swimming-pool water - with transparent analyser determining transparency of water contained in it
Inventor: STELZER HANS VON
IPC: G01N33/18
Filed: 1974-04-26
Abstract: The process is designed to determine the proportion of disinfecting media in the water in swimming pools, and to compare this with desired values, using a circulating duct system for the water which is to be regenerated, and portions of this water led off from the system and metered in an analyser, wiht an indicator. The metering is effected by means of a transparent analyser, by determining the current light permeability of the analyser, including that of the water contained in it; this may be determined by means of a photo-cell. Regeneration, with the required addition of disinfecting media, can follow on the basis of the comparison of the actual and desired values. The pH value may also be determined int eh same analyser or a parallel one. Metering and regeneration can be fully automatic, with min. maintenance.
Patent DE-2421689-A1 (DE)
Title: Corrosion protection for motor vehicle - is achieved by provision of suitably sizedand located holes in structure
Inventor: WEDEMEYER ERNST AUGUST DIPL IN
IPC: B62D25/20
Filed: 1974-05-04
Abstract: Inclined surfaces in vehicle structures, and particularly enclosedd spaces which perspire during temp. variations, are susceptible to rusting through. It is found that corrosion is eliminated when small holes are bored in the upper part of the enclosed structure. However the size of hole is critical, if it is too small then the air balance and equalisation occurs too slowly, if it is too large, eddy currents occur. For this reason the size of hole must lie between 2mm and 20 mm in diameter.

Title: Pilot hole precision drill - shaft head cased and fitted with spiral and chisel bit
Inventor: DRESPA GERD
IPC: E21B7/28
Filed: 1975-02-17
Abstract: Rotary drill typically for precision or pilot bores in ground, to be followed by a reamed main hole is designed as a long shaft (5) whose outline forms a cylindrical casing (10) with imposed spiral (12). The height of the spiral section is much less than the diameter of the drill casing (10), and the drill is tipped with a chisel bit. Preferably the spiral should be rectangular in section. The pitch of the spiral should be approximately 1.5-3 times the casing diameter. Thus assuming a casing diameter of Dm, the sectional height of the spiral should amount to around 0.2 Dm. It is proposed that the casing should have a diameter of approximately 40 mm. The rectangular section of the spiral should be 7 mm wide and about 8 mm in height.

Title: Erasing mechanism for recording medium producing visual display - uses two magnetic fields at right angles in plane of recording
Inventor: FICHTER MANFRED
IPC: G01D15/00
Filed: 1975-04-15
Abstract: A magnetic recording disc or tape used to provide a visual display, forming part of a registering system for the operation of e.g. a vehicle, has an erasing system with two magnetic fields in the plane of the recording medium, with the direction of the field at right angles to each other. The erasing mechanism consists of a single coil (4) with a minimum of two limbs (2, 3) in the same plane, each preferably with a rectangular cross section (5). The two limbs intersect at a point outside the width of the recording track (6). The coil (4) can be supplied either with direct or with alternating current. When alternating current is used for the excitation, the alternating fields are made effective by improved eddy current dissipation.
